There is code to convert XML files to a JAR file, convert the JAR file to a byte array and transfer it as a input stream.

A receiver class reads the input stream and forms a JAR file and extracts the XML files.
Occassionally I am getting a ZIPException: invalid stored block lengths while trying to form the JAR file using the input stream.

I need some help to overcome this.

Error:

ApplicationXMLReceiver, I/O Error: ,

java.util.zip.ZipException: invalid stored block lengths
at java.util.zip.InflaterInputStream.read(InflaterInputStream.java(Compiled Code))
at java.util.zip.ZipInputStream.read(ZipInputStream.java(Compiled Code))
at java.util.jar.JarInputStream.read(JarInputStream.java(Compiled Code))at java.io.FilterInputStream.read(FilterInputStream.java(Inlined Compiled Code))
...

Thanks

Sorry, don't understand your problem Could you explain it some more.
The following is confusing:


form the JAR file using the input stream


I would interpret "form" as an output/creation step, so how is it connected to using the input stream?

Is the error occuring when writing to the jar file or when reading from it?

We have a utility (a class called called Jar) using which we create JAR files.

Server-end
I create a JAR and add 2 XML files to this JAR and convert this JAR to byte array and write a message to a message queue.

Client-end
Read the message from the queue... get the input stream and create a Jar file (utility... it has a constructor that accepts InputStream and converts it to a JAR).

I guess I am getting this problem when I am getting the problem when reading from the JAR.

Will this be due to 'byte[] buffer = new byte[4096];'... the JAR is pbly larger than this size?

Please reply at your earliest convenient time.
